PSU for i5 2400 + HD 6850?


So i'm about to order the components for a new pc and wanted a second opinion on the PSU before doing so. I ran the PSU calculator at Antec which indicated the EarthWatts 380 would be fine but wasn't sure if i ought to bump up to the 430 for good measure.

Here's where i'm at:

*don't intend on adding a 2nd GPU or overclocking

PSU: Antec EarthWatts Green EA-380D Green 380W Continuous power ATX12V v2.3 / EPS12V

CPU: Intel Core i5-2400
MOBO: ASRock H61M/U3S3
GPU: SAPPHIRE 100315L Radeon HD 6850 1GB
RAM: G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
HDD: SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM SATA
CASE: Rosewill Blackbone

In addition to the above, i'll likely have the following:
1x 80mm
2x 120mm
Possibly 1 more 500gb/1tb HDD down the road.

I don't having anything against bumping up to a higher wattage PSU aside from the fact that the 380 is such a good deal.

Any input would be greatly appreciated.

    I think you are really pushing it. I would feel safe with a ~450w PSU and a 6850 but probably not less. The 430 would be a better choice in my opinion. Give you a little headroom.
  2. I'm with anort on this one... you'd probably be pushing it with a 380. I'd feel a lot better with the 430...
